How???

Does 108 everyday with non labbed 32 pitch bravo's (on the limiters)

Did a best of 114 with some cut down & labbed 34's from B blades. Downhill with a tail wind.

Difuser ring cut off all props spinning inward.

A pair of Ilmor 625's w/ stk Bravo 1 4 blades will get you 120mph+.

130 w/ 625's

Sean,

Thats a totally different setup that Scott Conrad came up w/ using Stellings adjustable boxes & 5 blade Herrings. Doable but expensive as a retrofit. Definitely an option for a new build. Jay Pilini didn't build any Ilmor 32's w/ that setup.

i realize that, but for almost 10 mph, a set of props and ext boxes doesn't seem like a bad investment. people spend considerably more and get less all the time. and gaining that 10 mph and keeping the engine stock/warrantied is always a good deal.

I think Scot said he had $15k+ in that retro fit. If you add labor that would be fairly pricey.

If one had the money & the option to, building a new 32 w/ Ilmor 710's & the Stellings boxes would be the biggest bang for the buck since the boat comes w/ ext boxes standard. Ilmor 625's to 710's is less than $25k.

Ultimately the testing that Scot did & the fact he came up w/ several more mph just by moving the X dim is impressive. Not sure how comfortable to drive it would be for the less experienced pleasure cat owner. Remember Scot's a racer!
